The UDMCB is specifically designed to complement the highest performance NPMPC Nano PWM  drives and address the needs
for a more economical drives. It has the same form factor as the NPMPC and same connectivity.
One customized carrier board can be used for both modules.
Such a carrier board design enables customization of connectors, I/O configuration, STO and other safety related functions.
For prototype testing and carrier board design reference it is recommended to use the UDMPA.
The UDMCB is a slave that runs under any ACS EtherCAT® masters.
A comprehensive set of software support tools are provided for configuration, setup and tuning.

Drives
Type: digital current control with field oriented control and space vector
modulation.
Current ripple frequency: 40 kHz.
Current loop sampling rate: 20 kHz.
Current dynamic range: 1,500:1.
Programmable Current loop bandwidth: up to 5 kHz.
Commutation type: sinusoidal. Initialization with or without Hall sensors.
Switching method: advanced unipolar PWM.
Protection: Over and under voltage, Over current, Over-temperature, Phase to phase and phase to ground short (short circuit on one of the motor phases might damage the drive).

Supply
The module is fed by two power sources. A motor supply and a 24Vdc control supply. During emergency conditions there is no need to remove the 24Vdc control supply. (If STO is used, then there is also no need to remove th motor supply)..
Motor Drive Supply
Range: 12Vdc to 60Vdc or 12Vdc to 100Vdc,
Recommended range: 12-56Vdc for 60Vdc version, 12-96Vdc for 100Vdc version.
Current rating should be calculated based on actual load.
If regeneration resistor is required, it should be added in parallel to motor supply with activation at 62V for 60V version or 102V for the 100V version.
Control Supply
Range: 24Vdc ± 10%.
Maximum input current / power: 0.9A @21.6V/ 20W Without motor brakes.
Protection: reverse polarity. A 2A external fuse must be used.
